Hey! I made an other team a couple of days ago, and I decided to post it here. I used mostly heavy hitting mons with powerful attacks, and I find it a pretty decent team, but there's always something to improve, so here it is.
Lopunny @ Lopunnite
Ability: Limber
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Return
- High Jump Kick
- Healing Wish
- Substitute
My main sweeper, I use it mostly mid- or late game. It has an (in my opinion) average EV-spread with maximized Attack and Speed, the rest put into Defense. Return and High Jump Kick are its most powerful STAB moves, the latter of which can hit Mega Sableye super effectively. Healing Wish is for supporting other team members, mainly Volcarona or Hydreigon which are easy to wear down. Substitute is to avoid status, but I never used it, so maybe I should change it to Fake Out or Ice Punch. Since M-Lopunny is already really fast, Ice Punch would be a better option, to deal with annoying flying types not named Talonflame.
Volcarona @ Lum Berry
Ability: Flame Body
EVs: 72 HP / 252 SpA / 184 Spe
Timid Nature
- Quiver Dance
- Fire Blast
- Bug Buzz
- Giga Drain
Volcarona is my other main sweeper - sadly I can't really use it at its fullest potential at the lower ladder, since M-Lopunny mostly manages to KO everything. Lum Berry is my item of choice to avoid Toxic, paralysis or sleep. My plan was to switch it in late game, when its checks and counters are already eliminated, set up as many Quiver Dances as possible, than sweep, but it actually never happened yet, since I either couldn't set up, or didn't have to. Sometimes I also use it mid-game if it can KO something without a boost.
Hydreigon @ Life Orb/Choice Scarf
Ability: Levitate
EVs: 4 Atk / 252 SpA / 252 Spe
Mild Nature
- Draco Meteor
- Dark Pulse
- Flash Cannon
- Superpower
Hydreigon is a powerful wall breaker with Life Orb. Draco Meteor and Dark Pulse are its obvious STAB moves, and I decided to run Flash Cannon to deal with slower fairies except from Azumarill. Superpower is to hit Steel types hard, since it also has a decent Attack stat. I'm not sure about Life Orb, however, maybe I should switch it to Choice Scarf to get a powerful revenge killer, but then I would lost the opportunity to switch to Flash Cannon, when a fairy type comes in.
Starmie @ Life Orb
Ability: Natural Cure
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Hydro Pump
- Ice Beam
- Thunderbolt
- Rapid Spin
Because of Volcarona I needed a hazard remover. I wanted to keep the team more offensive, so I chose Starmie - they also have good type sinergy. Since Starmie is really frail, I try to keep it off the battle if it's possible, at least until the opponents hazard setter is alive. It has a standard moveset I think, with Hydro Pump for powerful, but somewhat unreliable STAB, BoltBeam coverage and Rapid Spin.
Landorus-Therian @ Leftovers
Ability: Intimidate
EVs: 252 HP / 240 Def / 8 SpD / 8 Spe
Impish Nature
- Stealth Rock
- Earthquake
- U-turn
- Stone Edge
I also needed a hazard setter, and I decided to use Landorus-Therian, since it rarely let me down. It's the only mon on my team that runs a more defensive set, because I don't have a spinblocker or Defiant user, so it might have to do its job multiple times in a battle. Anyway I found, that it hits pretty hard even without attacking investment. Stone Edge can OHKO Talonflame, and Earthquake is its most powerful STAB. I might change U_turn to Knock Off, but I can't decide since both are really good moves, and I don't wanna lose the other three.
Scizor @ Choice Band
Ability: Technician
EVs: 248 HP / 252 Atk / 8 SpD
Adamant Nature
- Bullet Punch
- Bug Bite
- Superpower
- Pursuit
Scizor is my main check to fairies and dragons. Technician boosted Bullet Punch makes it an amazing revenge killer and a nightmare to fairies. I chose to run Bug Bite over U-turn because of the boost it gets from Technician. Superpower helps to deal with steel types. With Pursuit I can trap psychic and ghost types, which comes in handy since Aegislash is back for the suspect tests.
Here is also a replay, to see how the team works.
